I'm not sure how Hillary offering the VP slot to Obama is "reaching out" in this case, given that she was in second place when she made the "offer." Typically, the person in second place is in no position to offer a subordinate role to the person in first place.

More likely, as many commentators noted, Hillary's "offer" was simply an attempt to obscure Obama's frontrunner status.

Oh, and guys: the term "tap" has long been used in politics to mean "nominate" or "choose" for an office. I don't know why the press should stop using it, simply because it currently has another meaning which may, given the shelf life of slang, vanish in a few years.
